Embodiment

[0137] The production method of the present invention will be described more specifically based on examples. However, the present invention is not limited to the following examples. In addition, in the following description, the description of the part related to the process with which the manufacturing method of a glass product is comprised normally, such as a forming process, an annealing process, and a cutting process in the manufacturing method of this invention, is abbreviate|omitted.

[0138] figure 1 is a schematic diagram of the production method of the present invention. figure 1 In the melting process, the exhaust gas 12 generated from the glass melting furnace 10 is supplied to the cooling tower 16 at a gas temperature of 135 to 155° C. through the bag filter 14 .

[0139] In the cooling tower 16, the cooling water 18 is sprayed with 1-3m 3 / h, three total 3 ~ 9m 3 / h Spray and contact the exhaust gas 12.

[0140] Also, the cooled exhaust gas 20 cooled to 65˜90...

Abstract

This invention provides a process for producing a boron-containing glass product, comprising a step that, even when sulfur is contained at a high concentration in a waste gas, can simultaneously remove sulfur and boron from the waste gas. The process comprises a cooling step of cooling a waste gas containing sulfur and boron generated from a glass melting furnace with cooling means that bring thewaste gas into contact with a cooling liquid to give a cooled waste liquid and a cooled waste gas containing sulfur and boron, and a removing step of bringing the cooled waste gas with a contact liquid by contact means to remove sulfur and boron from the cooled waste gas and thus to obtain a waste liquid, after contact, containing sulfur and boron, and a clean gas.

Description

technical field [0001] The invention relates to a method for manufacturing boron-containing glass products and a method for purifying waste gas produced during the manufacture of boron-containing glass products. Background technique [0002] Glass products are made by feeding powdered glass raw materials and cullet into a glass melting furnace, heating them with a burner flame burning liquid fuels such as heavy oil and kerosene, or gaseous fuels such as LPG to form molten glass, and forming them by float method, etc. And get. Here, exhaust gas including vaporized substances such as sulfur compounds and boron compounds contained in glass raw materials, liquid fuel, or combustion exhaust gas including components in gaseous fuel is generated from the glass melting furnace. Especially when using a defoaming agent containing a sulfur compound, or when producing boron-containing glass products represented by non-alkali glass and borosilicate glass, the exhaust gas contains relati...
